The specific use mode and function of the embodiment are as follows:

when the cable fixing device is used, firstly, a cable needing to be overhauled is placed on an annular groove of the roller, then one hand holds the connecting sleeve 2, the other hand pushes the connecting rod 3, the pushing of the connecting rod 3 is stopped after the two groups of rollers clamp the cable, the L-shaped sliding rod 301 is driven to move when the connecting rod 3 is pushed, the L-shaped sliding rod 301 automatically stretches and retracts to adjust according to the track of the one-way teeth when moving, so that the connecting rod 3 moves more smoothly, the groove of the one-way rack and the inclined block are matched to form a self-locking structure of the connecting rod 3, the roller between the supporting seat A10 and the supporting seat B11 clamps the cable, then the connecting sleeve 2 is held by hand to push the cable to move integrally, the roller rotates along the outer side of the cable, the roller is convenient to move on the cable, and is fixed through a bolt when the cable is integrally moved to a position needing to be maintained, the connecting sleeve 2 is supported through the telescopic mechanism 1, the cable is convenient to maintain after being fixed, two groups of equipment are arranged, the other group of equipment is arranged on the cable according to the operation steps, the two groups of equipment are matched to complete the support of the cable, the cable between the two groups of equipment is cut off through a tool, the test pencil 9 is taken out from the connecting rod 3 to carry out power supply detection on the cable, and the cable is cut off to be subjected to insulating skin cutting;

when the insulation skin of the cable needs to be cut, firstly two groups of surrounding cutting mechanisms 6 are installed on the limiting rod 5, then the surrounding cutting mechanisms 6 are fixed on the limiting rod 5 through nuts, then the two limiting bolts 8 are rotated according to the thickness of the insulation skin to limit the cutting thickness of the cutting blade A605, the damage to the interior of the cable caused by excessive cutting of the cutting blade A605 is reduced, then the two pressing blocks 604 are pressed, the two cutting blades A605 are moved inwards at the same time, so that the two cutting blades A605 are in contact with the insulation skin of the cable, then the sliding block 602 is pushed to slide on the supporting piece 601, at the moment, the cutting blade A605 performs surrounding cutting on the insulation skin, and the sliding rod B702 is pushed to enable the cutting blade B703 to perform transverse cutting on the insulation skin;

when dismantling the gyro wheel from the cable, at first promote catch bar 4, two L shape slide bars 301 are inboard at the extrusion of taper hole and are removed for one-way rack is kept away from to the sloping block on the L shape slide bar 301, thereby removes the auto-lock of connecting rod 3, then promotes connecting rod 3 and dismantle the gyro wheel.

The embodiments of the present invention have been presented for purposes of illustration and description, and are not intended to be exhaustive or limited to the invention in the form disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiment was chosen and described in order to best explain the principles of the invention and the practical application, and to enable others of ordinary skill in the art to understand the invention for various embodiments with various modifications as are suited to the particular use contemplated.
